Roman has a rival as Russian builds world’s most expensive yacht

It boasts seven decks, two helicopter pads and storage space for a submarine. Yet the most significant fact about the secret yacht-building project in Genoa is the price tag – a record-breaking £140 million.

Measuring 438 feet long, the 60-strong crew of the world’s most expensive privately-owned yacht will entertain guests in 15 state rooms fitted with the latest entertainment systems, gold and marble bathroom fittings and Jacuzzis.
